Some suggestions for future updates:
- At some point, you should be able to interact with Eri in the morning, either waking her up nude on weekdays (and then walking to school with her) or talking with her in her pajamas on weekends.
- Yui's level 2 and level 3 scenes should be swapped. It's jarring for Eri's level 2 scene to be getting stuck under her bed, Onori's level 2 scene to be skinny-dipping, and Yui's level 2 scene to be hardcore incest sex with shocking backstory revelations. In comparison, Yui jerking off on you in your sleep is much more tame, much more in-line with the other two Level 2 scenes in terms of intensity. You wouldn't even have to change the follow-up dialogue much, since both scenes involve Riko pretending to be asleep.
- A future scene should have Riko fuck Onori, as karmic revenge for the three times she molests you in this build (maybe after Riko levels up Masculine Riko and Boisterous Riko a few times). Maybe he could even team up with Yui and DP her, fuck that tomboy ass and pussy at the same time.
